Abstract
A method for determining a pulse duration Tof a 90° pulse in a nuclear magnetic measuring method. A signal generator has a known generator resistance R, wherein a coil has a coil impedance Zwith a coil resistance Rand a coil reactance X, wherein a coupling circuit has an adjustable matching capacitance Cand an adjustable tuning capacitance C, and wherein the medium has a Larmor precession having an angular Larmor frequency ω. The time needed for determining the pulse duration Tof the 90° pulse is reduced by the matching capacitance Cand the tuning capacitance Cbeing set so that the angular resonance frequency ωcorresponds to the angular Larmor frequency ωand by power matching being present between the signal generator and the coil. The coil resistance Ris determined and the pulse duration Tis determined as a function of the coil resistance R.
